The invention provides a sophisticated application programming mechanism and technique that makes referencing data look as if the data is dynamically allocated by the process. The invention also provides a mechanism whereby all the persisted data is shared across all processes on the same computer that access it. In order to achieve these advantages, the invention creates small, process specific structures on demand as the program accesses the references from the persisted data and makes use of the underlying memory mapping and linking technologies inherent in modern Operation Systems. The technique is especially useful in large data warehouses, or planning data repositories, where it simplifies preparation for the sharing of non-volatile data between instances of an application, permitting sharing of data between different applications, and reducing the size of the data shared. It allows for the data to be highly referenced internally while not requiring the extra memory used by pointer swizzling at runtime.
